Fake wifi conection, but when wired connection works

English Network/Internet

When I run ping 1.1.1.1 in my OpenSUSE Leap 15.5 when there is no cable connection but kde claims that it is connected to the internet , I get:

$ ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) Bytes an Daten.
Von 192.168.0.4 icmp_seq=1 Zielhost nicht erreichbar

but ip a says like KDE that I am connected to the internet:

 wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 1:11:11:11:11:11 brd ff:ff:ff:ff:ff:ff permaddr 22:22:22:22:22:11
    altname wlo1
    altname wlp1s0
    inet 192.168.0.8/24 brd 192.168.0.255 scope global dynamic noprefixroute wlan0
       valid_lft 2828sec preferred_lft 2828sec

Note that I am able to connect to opensuse.org if I use a cable connection.

Not, that is not what “ip address” is saying, it is telling that it has an interface that has address 192.168.0.8 and that the interface is UP, nothing more than that.

Likely that 192.168.0.8 address was acquired using DHCP from the WLAN Acces Point with address 192.168.0.1, can you ping that?

If so, try “tracepath 1.1.1.1”.

You can also try “ip link”

Your “ip link” and “tracepath” output should that the WiFi connection to your Access Point is fine.

1.1.1.1 is not a normal IP address so if you want to debug why this connection is not working better show us what a ping/tracepath to 195.135.221.26 or another well know website gives.

It works now. No idea what it was failing.
Maybe false alarm of my homeserver failing at ssh.
